General Statement

Planet Earth is our home. Humans live on land which occupies only 29 percent of Earth’s surface. The remainder is covered by ocean. An envelope of air surrounds Earth. These realms—the lithosphere, hydrosphere, and atmosphere—form the environment for life on this planet. The study of these realms and their interactions with the biosphere and human systems, comprises the Geosciences—Atmospheric Sciences, Geography, Geology and Geophysics, and Oceanography.

The College of Geosciences is home to four academic departments in these disciplines and interdisciplinary academic offerings in Environmental Programs and Water Management and Hydrological Sciences. To sustain human society into the future will depend on the innovation and application of discovery in the geosciences. The interdisciplinarity of our field is essential to solving today’s grand challenges—understanding global climate change, maintaining air and water quality, and producing adequate energy and food supplies for all people.

Geography studies humans and their interactions with the environment from a spatial perspective using a range of methods and geospatial technologies. As an interdisciplinary field, it synthesizes knowledge from the other geosciences as well as from the social and biological sciences. Geology and Geophysics deals with the processes and forces acting at the surface and within Earth: with the materials of Earth, its forms and structures, the history of its development and the evolution of life on its surface and in its waters, and the physics of solid Earth. This includes the measurement and understanding of its internal structure, physical properties, and plate motions and their effect on continents and ocean basins. It also includes the detection of natural resources through remote sensing. Atmospheric Sciences includes studies of weather/meteorology, climate and climate change, and air quality through the disciplines of atmospheric dynamics, atmospheric physics, and atmospheric chemistry. Oceanography is the study of the marine environment and its inhabitants. The distribution and nature of marine life, the development of ocean basins, the chemistry of ocean waters, and the dynamics of water masses are the major elements of Oceanography.

Atmospheric Sciences, Geography, Geology and Geophysics, and Oceanography offer BS, MS, and PhD degrees; a BA is also available in Geology. The College offers two interdisciplinary BS degrees through Environmental Programs: a BS in Environmental Studies and a BS in Environmental Geosciences. In addition, Geography offers a BS in Geographic Information Science and Technology and two University Studies BS degrees (concentrations in Geography and Geographic Information Science and Technology). The College offers an online Master of Geosciences degree with specialized tracks in Geographic Information Science and Technology, Petroleum Data Management, and ocean data science, in addition to hosting a graduate program leading to an MS and PhD in Water Management and Hydrological Sciences. 

College of Geosciences faculty members participate in research on a broad front of both basic and applied subjects. The College is the Science Operator for the International Ocean Discovery Program, which is the largest geosciences research program in the world and explores the structure and history of sediments and crust beneath the sea floor. The College also hosts the Texas Sea Grant program. Other coordinated research programs in the College include the Geochemical and Environmental Research Group, the Center for Tectonophysics, the Berg-Hughes Center for Petroleum and Sedimentary Systems, the Center for Atmospheric Chemistry and the Environment and the Texas Center for Climate Studies. Field work takes both faculty and students around the world to learn about the wide range of environments and processes affecting Earth and its inhabitants. Consequently, faculty bring to their classes the excitement of discovery, state-of-the-art scientific equipment, a knowledge of useful applications to human problems, and good working relations with industry and governments, all of which can help the undergraduate prepare for a rewarding career. 

Career opportunities for graduates in the Geosciences are evolving dynamically—in industry, business, education, and government at all levels. Geosciences professionals apply highly desirable and marketable skills in several areas: research essential to understanding an increasingly unpredictable Earth; search for sustainable energy, mineral, and water resources; prediction and mitigation of natural hazards; deployment of geospatial techniques in numerous domains; informing wise environmental policy development and decision-making; and teaching in high schools, colleges, and universities.

Double Major

Students in the College of Geosciences may elect to have two major fields of study within the College, or they may elect to have a major in the College of Geosciences in conjunction with a major in another college provided that both majors lead to the same baccalaureate degree; that is, both must lead to a BA or to a BS. Approval is required by the Associate Dean for Academic Affairs in the College of Geosciences, the current major department, and the proposed major department. Additional permissions may be required if a student elects a double major in two different colleges. Students seeking to double major must have a 3.0 overall GPA and a 3.0 in the current major at the time of application. Students pursuing a double major must:

  1. satisfy all University and College requirements;
  2. successfully complete departmental requirements in each major, if both majors are in the College of Geosciences; and
  3. in cases where one major is in the College of Geosciences and the other is in another college, the student must successfully meet the major field of study requirements for each area as determined by each college.


Students may choose to complete a minor in the College of Geosciences. All minors will require not less than 15 hours and not more than 18 hours in the discipline; at least 6 hours must be upper-division courses in the discipline. Each student choosing to complete a minor must contact the department offering the minor to determine if specific courses are required.

Change of Major and Transfer Students

Change of Major students are welcomed in the College of Geosciences. Students seeking entry from another major must be in good academic standing, meet approval of the Associate Dean and have shown interest in their new intended major by taking at least one course in the subject. To begin the Change of Major process, students should first contact the academic advisor in the department to which they wish to change. If the student meets minimum criteria, he or she will be referred to the Associate Dean for approval and processing.

Students are welcomed to transfer into the College of Geosciences from other universities and community colleges. Overall, the College of Geosciences requires a prospective student to have completed, or be in progress of completing, a minimum of 24 hours from a list of courses specific to each major outlined on page 56 of this catalog with a cumulative minimum GPA of 2.5.  The College of Geosciences is also participating in the Program for Transfer Admission as well as the Program for System Admission in cooperation with Prairie View A&M University, Tarleton State University, Texas A&M International University, Texas A&M University-Commerce, Texas A&M University–Corpus Christi, Texas A&M University–Kingsville, West Texas A&M University and Texas A&M University–Texarkana.

Teacher Certification

The need for highly qualified teachers is high in the state of Texas. Students in the College of Geosciences are encouraged to consider pursuing a career in teaching. A number of pathways to certification are available. Interested students should consult with their advisors early in their programs and consult options outlined on the certification website. The college collaborates with the College of Science and the College of Education and Human Development on the aggieTEACH Program and in the University Studies degree program in secondary science teaching. Students in Geography may obtain composite social studies certification with a specialty in Geography through the Secondary Post-Baccalaureate Certification Program (8-12) or alternative certification options.

University Honors Programs

The College of Geosciences participates in the University Honors Programs, which is described in detail at Honors and Undergraduate Research.

International and Cultural Diversity Requirement

Texas A&M University requires its students to meet an International and Cultural Diversity requirement as part of the Graduation requirements. Meeting this requirement will require the careful selection of courses. The student is directed to Requirements for a Baccalaureate Degree section of this catalog for detailed information regarding this requirement and is also encouraged to seek the advice of the student’s academic advisor.
